Cythera on PC

Well, I tried to run Cythera on my PC using a program called Executor 2.0. Installing worked, but then it says "Install Thread Manager" and I did. But it still doesn't work. Is there any way to fix this? Or is there any other Macintosh emulator out there?

I saw that this had been posted before, but that was 2000 so I figured maybe Executor has made some progress since then.

Thanks

PS. Even it if DOESN'T work with any other emulator, could you please tell me of those you know of?
